Statistical codes in the Australian Harmonized Export Commodity Classification (AHECC) and the Customs Tariff classifications have been revised with new codes in effect from the January 2014 issue of this publication. The changes result from the introduction of new statistical codes separately identifying pharmaceuticals in Chapter 30 and carpet in Chapter 57 in both the AHECC and the Customs Tariff. There are also statistical code changes in the Customs Tariff identifying carpet underlay in Chapters 39 and 40. The changes will not impact directly on the presentation of statistics in this publication but will impact on detailed import and export statistics available on request.
